Thanks Szabolcs,
In fact, today the whole thing seems to work the following way
In[1]:= Needs["Utilities`Package`"]
(* functions - names- in "Utilities`Package`" *)
In[2]:= Names["Utilities`Package`*"]
Out[2]:= {"FindPackages", "FullPath", "PackageInformation"}
(* Looks up the HeaderInformation in the package "myContext`myPackage`"*)
In[3]:= PackageInformation["myContext`myPackage`", PackageInformation["myContext`myPackage`"]]
Out[3]:= (* All info in the header of "myContext`myPackage`". Including "Context", "Title", "Author", "Package Version", "Mathematica
Version", "Copyright", "History", "Summary", "Keywords", "Contents",
"Discussion", "Sources", "Warning", "Last modification", and so on*)
Off topic comment
The actual package belongs to a large application that I wrote in 2002, which makes heavy use of Combinatorica. I am having a hard time in recovering (and revamping) it after 10 years, to make it work in the newer versions. Among other difficulties: the whole old fashioned documentation and Help is nearly unusable.
Thanks again.

This function was probably part of the package mentioned here:
http://mathematica.stackexchange.com/a/699/12
The package is not part of Mathematica any more but it can still be downloaded from the Wolfram Library Archive.
